Naming alkenes and alkynes
Alkenes are named after the parent alkane by replacing '-ane' of the alkane by '-ene'. Alkynes are named after the parent alkane by replacing the suffix '-ane' of the alkane by '-yne'. Thus, Suffix for alkenes: -ene Suffix for alkynes: -..
..Alkyne, Alkene, Alkane - Comparitive Table
Alkanes Alkenes Alkynes General formula CH n H 2n+2 CH n H 2n CH n H 2n-2 Naming All the members end with 'ane' All the members end with 'ene’ All the members end with 'yne’ Physical state Members having 1-4 carbon atoms ..
From alkynes
Alkenes can be easily obtained by hydrogenation of alkynes. An alkyne on controlled hydrogenation with hydrogen in the presence of Ni or Pd at 200C give corresponding alkene. C n H 2 n - 2 + H 2 ..

Laboratory Preparation of Alkynes
There are only a few methods available for the preparation of alkynes, in contrast to alkanes and alkenes. These are given bel..
Acidic hydrogen in 1-alkynes
Hydrogen atoms in ethyne and 1-alkynes, linked to the carbon atom having a triple bond on it, are acidic in nature. For example, ethyne (acetylene) is a weak acid: weaker than water but stronger than ammonia. This may be explained as follows: The -electrons are more weakly bound than ele..
Electrophilic addition reactions
Carbon-carbon triple bond, C=C, is a combination of one and two bonds. Alkynes give electrophilic addition reactions as they show reactivity due to the presence of bonds. This property is similar to alkenes but alkynes are less reactive than alkenes towards ..

This Tutor Vista is GREAT! loved this session, it helped me heaps.
It was a great pleasure working with this tutor was able to take me through the steps of my math problems which was very helpful because since I don't have lots of experience with math by the tutor doing the steps it helps me understand a great deal. Im so excited that Im finally getting this amazing service. We got so much done. thank you.
Tutor Vista tutors actually helped me to think through some of the problems instead of just doing them for me.Now i am more confident with math ,Thank you all
This is very helpful and explains everything thoroughly. when asked to do problems slowly, tutors did them very thoroughly and even went extra mile to explain how and why with text - I just bow down to Turor Vista
